This Axios article describes what the Senate is planning to do tomorrow on Healthcare. First they'll vote on a motion to proceed on the House Republican Healthcare bill, the AHCA. Assuming it passes, they'll vote on the Senate Republican Healthcare bill, the BCRA. If the BCRA fails, which it probably will, they will then vote on a straight repeal of Obamacare. If that too fails, which it probably will, then they'll start debating various amendments to the House bill (the AHCA) and see where they can go from there.
But all of this is contingent on successfully voting on the motion to proceed. So my question is, have any Republican senators publicly announced their intentions to vote no on the motion to proceed tomorrow? Because it just takes three Republican senators to vote no and the motion to proceed will fail.
